I have a content type that is using a multi-line field with a text-editor appearance. When I create a content item using this content type, I am unable to add hyperlinks, images, or text-formatting. I believe this is because the z-index on the container (.ReactModal__Overlay) is set too high. It's set at 1200 and needs to be 1052 for the elements in the toolbar to appear on top of it. How can I change this z-index? It looks like it's being set in the iframe. Another issue I'm having with the toolbar is that the other options in it (bold, italicize, underline, etc.) only work when using Firefox.
